Heat problems
I have a 1996 XJ 4.0. I recently did my own coolant flush and put a new thermostat and mixing valve in along with thermostat housing. I seemed to have gotten air in the system so I brought it in to get a real coolant flush. It has been incredibly cold here in Minnesota lately but even before that the heat wasnt keeping up very good. Both before and after the flush and new parts my temp gauge only gets up to 1/4 on the dash, im not sure if this is normal or not? I put a 180 or 185 stat in which is what was previously in there. Now when i drive down the road or rev the engine it will blow warm/hot air out but when I come to a stop light it blows cold/luke warm air. I havent tried flushing or replacing the heater core yet. do these symptoms seem like they are heater core related or something else?

Yeah, that's about right. But in very cold weather, it could be lower.
You can verify actual temp with an IR gun aimed at the thermostat housing when fully warmed up.

True. However, my experience with the IR gun is, that temps are all over the place, even on the thermostat housing and measured from close distance....mixed feelings about that.

Also, don't shy away from eliminating the heater control valve with a piece of tubing and plugging the vacuum line.
